Retinal vasculopathy with cerebral leukocencephalopathy and systemic manifestations (RVCL or RVCL-S, also previously known as retinal vasculopathy with cerebral leukodystrophy, RVCL; or cerebroretinal vasculopathy, CRV; or hereditary vascular retinopathy, HVR; or hereditary endotheliopathy, retinopathy, nephropathy, and stroke, HERNS) is an inherited condition resulting from a frameshift ...
Hemianopsia. Hemianopsia. Paris as seen with full visual fields. Specialty. Ophthalmology, neurology. Hemianopsia, or hemianopia, is a loss of vision or blindness ( anopsia) in half the visual field, usually on one side of the vertical midline. The most common causes of this damage are stroke, brain tumor, and trauma.
Oculomotor nerve palsy. Oculomotor nerve palsy or oculomotor neuropathy [1] is an eye condition resulting from damage to the third cranial nerve or a branch thereof. As the name suggests, the oculomotor nerve supplies the majority of the muscles controlling eye movements (four of the six extraocular muscles, excluding only the lateral rectus ...
Claude's syndrome. Claude's syndrome is a form of brainstem stroke syndrome characterized by the presence of an ipsilateral oculomotor nerve palsy, contralateral hemiparesis, contralateral ataxia, and contralateral hemiplegia of the lower face, tongue, and shoulder. Claude's syndrome affects oculomotor nerve, red nucleus and brachium conjunctivum.
Ocular ischemic syndrome is the constellation of ocular signs and symptoms secondary to severe, chronic arterial hypoperfusion to the eye. Amaurosis fugax is a form of acute vision loss caused by reduced blood flow to the eye; it may be a warning sign of an impending stroke, as both stroke and retinal artery occlusion can be caused by thromboembolism due to atherosclerosis elsewhere in the ...
Hemispatial neglect is a neuropsychological condition in which, after damage to one hemisphere of the brain (e.g. after a stroke ), a deficit in attention and awareness towards the side of space opposite brain damage (contralesional space) is observed. It is defined by the inability of a person to process and perceive stimuli towards the ...
Rizzo points out that his study did not show cause and effect — it just found a link. “Hopefully, it will prompt a much larger study to examine whether there's cause and effect,” he says.
Hemifacial spasm. Hemifacial spasm ( HFS) is a rare neuromuscular disease characterized by irregular, involuntary muscle contractions ( spasms) on one side (hemi-) of the face (-facial). [1] The facial muscles are controlled by the facial nerve (seventh cranial nerve), which originates at the brainstem and exits the skull below the ear where it ...
